Allparts Switchcraft Stereo Jack Plug

These are the skeleton type, which have a very tight and reliable spring connection. I have been using this type for many years, and the only imaginable problem could be if you use it with a metal chassis or box. The outer connection is then grounded to the chassis or box. Fine if a good ground is what you want (I do in this case), but a problem if you need a ground lift. They are also the "Industry Standard" for stomp boxes or guitars with active electronics, where the battery is connected to the "Ring" terminal. I've always found these to be extremely reliable, and far better than the moulded plastic body type. Plastic body is better for ground lift.
